Question

I have no idea how to do any of these so please explain I'm already struggling and school just started

1.
$5g + h = g$
solve for g
2.
$y = mx + b$
solve for m

3.
$3y + z = am - 4y$
solve for y

4.
$km + 5x = 6y$
solve for m

5.
$\frac{3ax - n}{5} = - 4$
solve for x

6.
$\frac{by + 2}{3} = c$
solve for y

7.
$at + b = ar - c$
solve for a

​

Answer 1

Answer:

See below!

Step-by-step explanation:

1. 5g + h = g

4g = -h

g = $-\frac{h}{4}$

2. y = mx + b

y - b = mx

m = $\frac{y - b}{x}$

3. 3y + z = am - 4y

7y = am - z

y = $\frac{am - z}{7}$

4. km + 5x = 6y

km = 6y - 5x

m = $\frac{6y - 5x}{k}$

5. $\frac{3ax - n}{5} = -4$

3ax - n = -20

3ax = n - 20

x = $\frac{n-20}{3a}$

6. $\frac{by+2}{3}= c$

by + 2 = 3c

by = 3c - 2

y = $\frac{3c-2}{b}$

7. at + b = ar - c

at - ar = -b - c

a(t - r) = -(b + c)

a = $-\frac{b+c}{t-r}$
